PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

The Complexion Gap: The Economic Consequences of Color among Free African Americans in the Rural Antebellum South [PDF]

open access: yes
Historians of U.S. race relations typically portray southern whites as reluctant to recognize or act favorably upon complexion-based differences within the African American community.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

open access: yesFEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...

Am I Still Too Black For You?: Schooling and Secular Change in Skin Tone Effects [PDF]

open access: yes
Analysts disagree about whether the Civil Rights/Black Power eras lessened the influence of skin tone on education. The paper finds that, holding family background constant, the educational disadvantages of dark and very dark blacks persisted between ...

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

BlacKkKlansman reverses film's historic power narrative between Blacks and Whites

open access: yes, 2018
Spike Lee's new film about the infiltration of the KKK by a black police detective in the 1970s, BlacKkKlansman was released this month. Christine Gallagher writes that not only does the film make allusions to the America of Donald Trump, it also ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Long-Run Convergence of Ethnic Skill Differentials [PDF]

open access: yes
This paper investigates if the ethnic skill differentials introduced into the United States by the inflow of very dissimilar immigrant groups during the Great Migration of 1880-1910 disappeared during the past century.

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

open access: yesFEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Take the money and run: Economic segregation in U.S. metropolitan areas [PDF]

open access: yes
Compared to racial segregation, economic segregation has received little attention in recent empirical literature. Yet a heated debate has arisen concerning Wilson's hypothesis (1987) that increasing economic segregation plays a role in the formation of ...
